IMPROVEMENT IN STEAM COTTON-PRESSES.

Specification forming part of Letters Patent No. 153,839, dated August 4,1874; application filed J unc 15, 1874.

To all whom it may concern:

Be it known that I, EDMUND L. MORSE, of St. Louis, St. Louis county, Missouri, have invented acertain Improved Cotton-Press, of which the following is a specification:

My improvement consists in the combination of one or more steam pistons and toggle, substantially as shown, to give the required movement to the rising platen.

In the drawings, Figure l is a perspective view of the machine. Fig. 2 is one-half in elevation and the other half in vertical axial section. Fig. 3 is a View similar to Fig. 2, showing the press constructed with two steamcylinders.

A is the base, and B B the uprights or pillars supporting the upper platen O and the superstructure. D is an opentopped steamcylinder, and E a piston working therein, the piston being raised by the pressure of steam beneath it, and carried down by its own weight and that of its attachments, when the steam exhausts from the cylinder. To the top of the piston are pivoted two pitmen, F F, whose upper ends are pivoted to two toggle-levers, G G, whose outer ends have pivot connections to the cylinder top. H H are toggle bars or links, whose inner ends are pivoted to the le-' vers G G, between the ends of the latter. The outer ends of these links are pivoted to the upper ends of the lifting-rods I, of which one extends upward from each corner of the platen J. The upper ends of the lifting rods are connected together by horizontal staybars K K, which carry at their mid-length anti-friction rollers L, traveling in vertical slots M, in the vertical frame N, whose top n acts as a guide for this piston-rod O. The stay-bars K prevent the upper ends of the lifting-rods being spread outward under the action of the toggle, and also, by reason of the anti-friction rollers M, confine them to a direct vertical movement.

In Fig. 3 is Shown duplicate cylinders D P platen. J while it is in its lower position, (see Fig. 2,) and the steam is then admitted beneath the piston. As the piston rises it swings the toggle-levers G G upward and outward, and raises the platen J with consequently decreasing speed and increasing power, as the resistance of the bale to compression becomes greater, owing to its contraction, as will read ily be understood by examination of the toggle device. The platen J has end guides 7' working in grooves in thebase.

By this arrangement a piston of much smaller area may be made to answer than if it were coupled directly to the lifting-rods, because when the cot-tonis very tightly compressed. so as to ofl'er a very considerable resistance to any further compression, the piston is acting on the lifting-rods, through the toggle, with the greatest power.

I claim as my invention- 1. The combination of an open-topped cylinder, D, piston E, pitman F, toggle-G H, and platen J, substantially as set forth.

2. The toggle-arm G, having links H pivoted to it at or near its mid-length, in combination with the pitman F, as and for thepurpose set forth.
